Modern lightbulbs use thinner filaments that are substantially more efficient than the thick one used in this bulb, but they don't last as long. Further, this particular bulb never gets turn off and back on again which I'm led to believe causes wear.
If it were turned off and back on it would likely be fine.
Always a fun segue into the Phoebus Cartel [1] which pushed for shorter lifespans for bulbs - including by mandating thinner filaments. They did it to keep people on the treadmill but it was actually a substantial improvement in energy efficiency.

- edb_123 5y agoI also do think that the filament thickness has a lot to say for longevity. I have a "decor type" large warm glowing light bulb with a quite thick and long filament that's been on for hours daily and turned on and off multiple times daily for 10 years now and counting. And yes, it is a real incandescent bulb, not LED :)
- CelestialTeapot 5y agoThe same game is still played today with LED bulbs (whether there's a cartel behind it or not, I do not pretend to know). See: https://www.youtube.com/watch?v=klaJqofCsu4 https://www.youtube.com/watch?v=klaJqofCsu4
